the proper driver would be the one from Focurite

it sounds like you are describing some sort of issue with your windows sound settings - check the sample rate there (by the way, in your previous pic you are requesting 44100 in reaper but then asking asio4all to resample to 48000?) and also check your recording levels in the windows sound settings, that might be the reason for loud input if you aren't using proper drivers.
